8.1 Sun zs Ports

The zs ports on the Suns are capable of going faster than 38400. The
divisor in the hardware timer chip is set so that

    baud_rate = 4915200 / ((divisor + 2) * 2 * 16)

Here are some example divisors

      Divisor   Baud Rate
        510        300
        62        2400
        14        9600
        6        19200
        2        38400
        1        51200
        0        76800

So, there is a little room for going faster.  Unfortunately, there is
not a 57600 baud rate available.  However, some modems can handle 76800
(such as the Telebit Worldblazer), and that can be set just as easily.
By default, the "-DFASTSZ" flag is set in the Makefile.hw file.
